Microsoft last month released Windows 10 April 2018 Update as a manual download and since then quite a lot of users rushed to upgrade their devices. It’s quite easy to upgrade any computer as the April 2018 Update is available on Windows Update with a manual check.

Microsoft is today expected to push the new Windows 10 April 2018 Update to devices via Windows Update, but it appears that not all devices will be receiving the update. A Microsoft Moderator (Agent) in the company’s community forum acknowledged a bug hitting Intel SSDs-powered computers.

The critical bug is affecting some systems with certain Intel SSDs and the computer hitting the bug fails to boot after upgrading to the April 2018 Update. The software giant is blocking the upgrade on these systems and the block will be lifted once a fix is delivered. You may need to roll back to the previous version of Windows 10 if your system fails to boot as there’s no workaround.

“Microsoft is currently blocking some Intel SSDs from installing the April 2018 Update due to a known incompatibility that may cause performance and stability issues. There is no workaround for this issue,” a Microsoft Agent said.

Microsoft is already working on a fix and the Windows 10 April 2018 Update will be soon shipped to all Intel SSD systems. Today is Patch Tuesday and Microsoft is also expected to address most of the reported bugs, and in addition to fixes, Windows 10 could also get security updates.

Today, Microsoft will begin pushing the new OS to compatible devices automatically via Windows Update, but in stages which means that not all users will receive the newest version of the OS today. Needless to say, the approach ensures a smooth upgrade process and gives Microsoft more time to resolve compatibility issues.

While this is a good approach, it would result in a slow rollout which means that most of the users might have to wait longer until the April 2018 Update becomes available for them. You can, however, download and install Windows 10 April 2018 Update manually by checking for updates, or with Media Creation and Upgrade Assistant Tools.
